DETAILED DESCRIPTION

Exemplary embodiments of the present disclosure will be described in more detail below with reference to the accompanying drawings. Although the exemplary embodiments of the present disclosure are shown in the drawings, it is to be understood that the present disclosure may be implemented in various forms and should not be limited by the embodiments set forth herein. Rather, these embodiments are provided so that this disclosure will be more fully understood and the scope of the disclosure will be fully conveyed to those of ordinary skill in the art.

It should be noted that, as used herein, the term “user” may refer to a human user, and may also refer to a non-human user, such as artificial intelligence, electronic equipment, and the like. Further, as used herein, the term “user's voice” may refer to a voice sound uttered by a human user, and may also refer to any sound generated by a non-human user, such as a recorded sound or music reproduced by a sound reproduction device, or a musical tone produced by an musical instrument, ambient noise, and the like.

The embodiment of the present disclosure provides a voice communication method applied to a transmitting side. As shown in FIG. 1, the method mainly includes steps 101 to 103.

101. Voice information is obtained.

In the embodiment of the present disclosure, when the transmitting side detects that there exists a voice in the external environment, the voice in the external environment, that is, the voice information in the embodiment of the present disclosure, may be obtained by a voice collecting unit deployed in the transmitting side. During the obtaining process, the voice collection unit may select a device that can be used for voice collection, such as a microphone or an electronic ear, to obtain the voice information. In the embodiment of the present disclosure, the detecting and obtaining of the voice information may be performed in any manner, which is not limited herein, and which may be selected according to requirements.

102. It is determined whether the voice information is uttered by a preset user.

In order to improve the security of voice communication and to avoid the influence of others on the security of the voice communication, in the embodiment of the present disclosure, after the voice information has been obtained in the foregoing step 101, the person who utters the voice information needs to be determined to detect whether the person is the owner or the holder of the device. Therefore, according to the present step of the method, it can be determined whether the voice information obtained in the foregoing step is uttered by a preset user.

Specifically, for determining whether the voice information is uttered by the preset user, it is possible to adopt, but not limited to, the following ways: for example, the determination may be made by using the audio in the currently obtained voice information. Specifically, audio features may be first extracted from the voice information and then compared with the pre-entered audio features of the owner, wherein the audio features of the owner may be extracted from a voice pre-entered by the user. Since each individual's audio features are different, the audio features of the current voice information may be compared with the pre-entered audio features of the owner. When the similarity exceeds a threshold set by the user, it is shown that the two voices are uttered by the same person, and then it is determined that the currently obtained voice information is indeed uttered by the preset user, and that the user who currently emits the voice in front of the transmitting side of the voice communication device is the preset user.

Certainly, in the embodiment of the present disclosure, the foregoing determining manner is only one implementation for determining whether the voice information is uttered by the preset user. The determining may also be performed in any other manner such as by determining the face or the behavior, for example, the action, which is not limited herein, and which may be selected according to requirements.

103. If the voice information is uttered by a preset user, the voice information is transmitted to a peer device; otherwise, the voice information is not transmitted.

Upon the determination of step 102, when it is determined that the voice information is indeed uttered by the preset user, it may be determined that the user who currently emits the voice is indeed the preset user, and that the voice may be transmitted. Accordingly, according to the present step of the method, the voice information may be transmitted to the receiving side corresponding to the transmitting side. For the transmission process and the transmission mode, any voice transmission mode may be selected, which may be wireless transmission or wired transmission. Here, the transmission mode and the transmission process are not specifically limited, and the implementation mode may be arbitrarily selected when the voice information is ensured to be accurate.

Upon the determination of step 102, when it is determined that the voice information is not uttered by the preset user, it may be determined that it is not the preset user who is currently emitting the voice, and that the voice information is not required to be transmitted. In this way, the problem of voice information leakage caused by other people impersonating the owner for voice communication may be avoided, and the security of the voice communication described in the embodiment of the present disclosure may be improved.

Therefore, according to the voice communication method applied to the transmitting side provided by the embodiment of the present disclosure, the transmitting side obtains voice information and determines whether the voice information is uttered by a preset user, and transmits the voice information when it is determined that the voice information is uttered by the preset user. In this way, the identity of the person who utters the voice information may be confirmed at the transmitting side, the problem that other people use voice device to affect the security of voice communication may be avoided, and the security of voice communication process may be improved as a whole. Moreover, when the voice information is not uttered by the preset user, the voice information is not transmitted, so that the problem of voice information leakage caused by other people impersonating the preset user to carry out voice communication may be avoided, at the same time, it can also avoid the transmission of independent voice information, thus reducing the overall power consumption, bandwidth consumption and other resources waste.

As shown in FIG. 2, another embodiment of the present disclosure further provides a voice communication method applied to a receiving side. As shown in FIG. 2, the method mainly includes steps 201 to 203.

201: Voice information transmitted from a peer device is received.

In the embodiment of the present disclosure, the peer device may be the transmitting side in the foregoing embodiment. For the convenience of description, in the embodiment of the present disclosure, as the peer device of the receiving side, the transmitting side in the foregoing embodiment is taken as an example. Therefore, after the transmitting side transmits voice information, the voice information may be received by the receiving side. Specifically, any one of the wireless or wired reception may be selected as the receiving mode, and certainly, it is necessary to ensure that the receiving mode of voice information at the receiving side matches the transmitting mode at the transmitting side, so as to avoid the problem of data loss.

202. A first environment information is collected, and it is determined whether the first environment information meets a voice output condition.

After the voice information is received in the foregoing step 201, in order to improve the security of the voice communication, and to avoid the case where the voice information is eavesdropped or stolen by others when the voice information is output, it is necessary to determine, before the voice information is output, whether the current environment meets a condition for outputting the voice information. Therefore, according to the present step of the method, first the first environment information may be collected, and then it may be determined whether the current environment condition meets the preset voice output condition according to the first environment information. The voice output condition may be preset by the user before performing the voice communication, and is used to define whether the current situation satisfies the voice output condition. As a manner of determining whether the first environment information meets the voice output condition, the identity of the recipient may be identified by facial recognition of the voice recipient. Specifically, the face features on the face of the voice recipient currently located at the receiving side may be collected by a face recognition unit, and then compared with the facial features of a preset receiving user, and the consistency between the two may be determined based on the similarity between the two, thereby determining the identity of the recipient based on the facial features. Certainly, in the embodiment of the present disclosure, the manner of determining whether the first environment information meets the voice output condition includes not only the foregoing manner, but also other manners. For example, the number of current voice recipients at the receiving side, or the distances from other people in the vicinity of the recipient to the recipient may also be used to determine whether the external environment meets the condition for outputting the voice information. Here, the determination method and type are not specifically limited, and may be selected according to actual needs.

203. If it is determined that the first environment information meets a voice output condition, the voice information is output, and otherwise, the voice information is not output.

After the determination of the foregoing step 202, when it is determined that the first environment information meets the voice output condition, it is indicated that the influence of other people on the security of the voice information is currently excluded in the vicinity of the receiving side, and voice output may be performed. Therefore, the voice information may be output by a voice output unit. Specifically, the voice output unit may be any speaker for outputting voice, such as an external speaker or a headphone.

After the determination of the foregoing step 202, when it is determined that the first environment information does not meet the voice output condition, it is indicated that if the voice information is outputted in the current environment, there is a possibility that the voice information will be obtained by others. Therefore, according to the present step of the method, the output of the voice information may not be performed. Certainly, after receiving the voice information from the transmitting side, the voice information may be saved in a preset storage medium to ensure that the voice information is output when the first environment information meets the voice output condition.

Therefore, according to the voice communication method applied to the receiving side provided by the embodiment of the present disclosure, the receiving side obtains the first environment information, determines whether the voice output condition is met, and outputs the voice information when the voice output condition is met; otherwise, no voice information is output. In this way, it is possible to determine, at the receiving side, whether the current environment meets the voice output condition when the voice information is to be output, and then to output the voice information when the current environment meets the voice output condition. When the voice output condition is not met, the voice information is not outputted, which can avoid the possibility that the voice information is obtained by others, and then ensure the security of the whole voice communication process.

According to the method shown in FIG. 3, another embodiment of the present disclosure further provides a voice communication method, which is applied to a transmitting side and a receiving side respectively. As shown in FIG. 3, the method mainly includes steps 301 to 306.

301. The transmitting side obtains the voice information.

In the embodiment of the present disclosure, the voice information communication is performed on both the transmitting side and the receiving side. The process and the manner in which the transmitting side obtains the voice information are consistent with the description in step 101 in the foregoing embodiment, and will not be described in detail here. Specifically, when the voice information is obtained, any voice input device, such as a microphone, may be selected.

302. The transmitting side determines whether the voice information is uttered by a preset user.

After obtaining the voice information according to the foregoing step 301, in order to ensure that the current user of the transmitting side is indeed the owner or the user who is allowed to use the transmitting side of the voice communication, that is, the preset user, in the embodiment of the present disclosure, it is also necessary to determine and identify the obtained voice information to confirm whether the current voice information is uttered by the preset user.

Specifically, determining whether the voice information is uttered by the preset user may be performed according to the following manners.

In some examples, it is determined whether the audio features of the voice information are consistent with those of the preset user. Specifically, when performing the determination, the audio features may be extracted from the currently obtained voice information, and then compared with the pre-entered audio features of the preset user. Since each individual's audio features are different, it is possible to determine whether the current voice information is uttered by the preset user by comparing the audio features. When performing the determination, the voice may be collected by a voice input device provided on the transmitting side, and then transmitted to the corresponding information processor for determination and identification. Here, the information processor and the voice input device are not specifically limited herein, and may be selected according to actual needs.

In other examples, the facial features of the person who utters the voice information are obtained and it is determined whether the facial features are consistent with those of the preset user. Specifically, when performing the determination, the facial image of the current user in front of the transmitting side may be collected, and the features of the image, that is, the facial features of the person who utters the voice information, may be extracted therefrom. Then, the facial features of the user and the pre-entered facial features of the preset user are compared to confirm whether the two are consistent. Since the facial features of each user are different, the recognition of the user may be performed by the facial features. In the process of face recognition and determination, the image may be collected by an image collection device, such as an electronic eye, provided on the transmitting side, and then the collected image may be transmitted to an information processor for image recognition and determination.

In still other examples, action features of the person who utters the voice information are obtained, and it is determined whether the action features are consistent with the action features of the preset user. Specifically, when performing the determination, the action of the user currently in front of the transmitting side may be obtained by an image collection device, such as an electronic eye, a pickup camera, or the like, provided on the transmitting side, and then the obtained image may be transmitted to the information processor for action recognition to determine whether the current user is the preset user. Before performing the determination, the action or gesture for determination may be pre-entered by a preset user such as the owner. In this way, the recognition of the preset user may be performed by the action recognition, which not only ensures the accuracy of the determination result, but also avoids the situation that the preset user such as the owner inadvertently triggers the voice communication, reduces the unnecessary voice transmission, and improves the accuracy of the voice communication.

It should be noted that, in the above three determination manners, any one of the above manners may be selected according to actual needs. Certainly, in order to further ensure the accuracy of the determination result, the above manners may also be combined. The combinations of the manners are not specifically limited herein, and may be selected according to actual needs.

303. If the transmitting side determines that the voice information is uttered by the preset user, the voice information is transmitted to the receiving side; otherwise, the voice information is not transmitted.

In the embodiment of the present disclosure, after the determination of step 302, there are two kinds of results, one of which is that the current voice information is not uttered by the preset user, and the second is that the current voice information is uttered by the preset user.

When it is determined that the voice information is not uttered by the preset user, it may be determined that it is not the preset user who is currently emitting the voice, and that the voice information is not required to be transmitted. Optionally, a reminder voice may also be transmitted to the receiving side to alert the recipient. In this way, the problem of voice information leakage caused by other people impersonating the owner for voice communication may be avoided, and the security of the voice communication described in the embodiment of the present disclosure may be improved.

When it is determined that the voice information is uttered by the preset user, it is indicated that the voice information needs to be transmitted to the receiving side and therefore, the current voice information may be transmitted to the corresponding receiving side by a transmitting device according to the present step of the method.

Further, when the voice communication according to the embodiment of the present disclosure is performed by the user, the voice information may be interfered by the ambient noise. Therefore, in the embodiment of the present disclosure, before the voice information is transmitted to the receiving side, the voice environment in which the transmitting side is located may be obtained, corresponding optimization processing on the voice information may be performed according to the voice environment, and the optimized voice information may be transmitted to the receiving side. The specific process may be as follows. The voice environment in which the transmitting side is located is obtained, and according to the obtained voice environment, it is determined whether there is noise in the vicinity of the transmitting side and the volume of the noise is determined when there is noise. Then, optimization processing on the voice information may be performed based on the voice environment in which the transmitting side is located. When obtaining the voice environment in which the transmitting side is located, the obtaining process may be based on a microphone provided at the transmitting side or on a device such as an electronic ear provided separately at the transmitting side for collecting environmental information. Specifically, the collection mode may be selected according to the actual needs. Meanwhile, the specific manner for optimizing the voice information may include: performing volume change processing on the voice information and performing noise reduction processing on the voice information. Here, the specific way to change the volume includes increasing the volume or lowering the volume. For example, when it is detected that the external noise is large, the current voice information may be subjected to noise reduction processing, and the volume of the voice information may be appropriately increased, thereby ensuring that the voice user can obtain a more accurate voice information when the voice is output.

304: The receiving side receives the voice information transmitted from the peer device.

In the embodiment of the present disclosure, the voice information is transmitted by the above-mentioned transmitting side. Therefore, the peer device that the receiving side receives the voice information from in this step is actually the transmitting side in the foregoing steps in the embodiment of the present disclosure. Therefore, after the collected voice information is transmitted at the transmitting side, it may be received at the receiving side according to the present step of the method. In the process of receiving the voice information at the receiving side, any mode may be selected as the receiving mode, and certainly, it is necessary to ensure that the receiving mode of voice information at the receiving side matches the transmitting mode at the transmitting side, so as to avoid the loss of data.

305. The receiving side collects the first environment information, and determines whether the first environment information meets a voice output condition.

In the embodiment of the present disclosure, in order to ensure that the case where others eavesdrop or others impersonate the owner of the apparatus is avoided when the user receives the voice information, in this step, the current environment at the receiving side needs to be detected to determine whether the condition for outputting the voice information is met.

In the embodiment of the present disclosure, the first environment information may be actually understood as the information about the environment in which the receiving side is located before the voice output is performed, and determining whether the first environment information meets the voice output condition may be performed as follows.

In some examples, it is determined whether there is only one voice recipient. Generally speaking, in the process of making a voice call, there may be a situation in which the user has other people around when receiving the voice. In order to ensure that the voice information is not obtained by others, it is necessary to determine the number of recipients currently in front of the receiving side. When there is more than one recipient, it means that there are other people besides the preset user, such as the owner, and the current environment does not meet the voice output condition. Specifically, the process of performing the determination may be performed by an image collection device, such as a pickup camera, an electronic eye, or the like, provided at the receiving side. The process of performing the determination may be performed by collecting images from the user currently in front of the receiving side, and identifying whether there is only one user.

In other examples, it is determined whether facial features of a voice recipient are consistent with facial features of a preset receiving user. Since each individual's facial features are different, the identity of the user can be recognized based on the face image recognition. Therefore, the image of the user in front of the receiving side may be collected by the image collection device provided at the receiving side, and then sent to the corresponding information processor for image extraction. After the facial features are extracted, the features are compared with the pre-entered facial features of the preset user, thus realizing the recognition function of the voice recipient.

In still other examples, it is determined whether distances from other users than a voice recipient to the voice recipient exceed a preset threshold. In the embodiment of the present disclosure, since other people may be present around the preset receiving user of the voice communication when the voice information is output, based on the principle of sound wave transmission, when the voice is output, it is necessary to avoid eavesdropping by other people. Therefore, the positions of the persons other than the current voice recipient may be collected by the image collection device provided at the receiving side, and then the distances may be calculated by the computing device. Then the distances from other users may be compared with a preset distance threshold by a preset processor. When it is determined that there are other users that have theirs distances smaller than the preset threshold value, it means that there are other users close to the receiving side in the vicinity of the actual voice information recipient, so that there may be a risk that the voice may be tapped by others after the voice is output. In this way, by comparing the distances from other users than the voice recipient to the voice recipient with the preset threshold, it is possible to avoid the situation that there are other users close to the receiving side and thus the voice is eavesdropped, thereby ensuring the accuracy of the voice communication.

In the above three determination manners, any one of the above manners may be selected according to actual needs. Certainly, in order to further ensure the accuracy of the determination result, the above manners may also be combined. The combinations of the manners are not specifically limited herein, and may be selected according to actual needs. For example, the three manners described above may be combined as follows. When the receiving side receives the voice information, it may first determine the number of users in front of the receiving side, and when there is only one user, it may determine whether the facial features of the current user are consistent with the facial features of the preset user. When it is determined that the facial features of the two are consistent, it is further determined whether the distances from other users in the vicinity exceed the preset threshold in addition to the current user. In this way, it is possible to determine whether the current environment meets the voice output condition by the number of voice recipients, the facial features, and the distances from others around, and it is possible to more reliably ensure the security of the voice information output.

306. If the receiving side determines that the first environment information meets a voice output condition, the voice information is output, and otherwise, the voice information is not output.

During the process of outputting the voice information, there may be situations that affect the security of voice communication at any time. For example, when someone else comes near the receiving side that is outputting the voice information, there may be situations where the voice information being output is heard by others. Therefore, in order to further improve the security of the voice communication during the process of outputting the voice information, the second environment information may be collected when the voice information is output. The second environment information may be understood as the information about the environment in which the receiving side is located during the process of outputting the voice information. Therefore, the output of the voice information is stopped if it is determined that the second environment information does not meet a voice output condition. Optionally, the output of the voice information is stopped, and the output is switched to a preset voice, which may be a voice preset within the system or pre-recorded by the user and is independent of the voice communication. In this way, when the external environment changes, other people cannot obtain the voice communication that the user is in progress.

Alternatively, an interference superimposed voice may be outputted if it is determined that the second environment information does not meet a voice output condition, the interfering superimposed voice being a voice in which interfering audio is superimposed in the voice information. In this way, while ensuring that the user can receive the voice information, the other people can only receive the interference voice, thus avoiding the safety problem of the voice communication caused by the voice leakage.

Further, in the output process of the voice information according to the embodiment of the present disclosure, in order to enable the output voice to be compatible with the environment, the output volume of the voice information may be controlled before outputting the voice, according to the environment information in which the receiving side is located obtained before the output. That is, the output volume of the voice information is adjusted according to the first environment information, and then the adjusted voice information is outputted. In this way, it is ensured that, when the external environment before the receiving side outputs the voice is quiet, the voice information can be outputted at a lower volume, thus avoiding being obtained by others and improving the security of voice communication. In contrast, when the external environment before the receiving side outputs the voice is noisy, the voice information can be outputted at a higher volume, thus reducing the external interference when the user receives the voice information.

An embodiment of the present disclosure further provides a voice communication apparatus applied to a transmitting side. As shown in FIG. 4, the apparatus mainly includes an obtaining unit 41, a determination unit 42, and a transmitting unit 43.

The hardware arrangement 900 includes a processor 906 (for example, a digital signal processor (DSP), a central processing unit (CPU), and the like). The processor 906 may be a single processing unit or a plurality of processing units for performing different actions of the flows described herein. The arrangement 900 may also include an input unit 902 for receiving signals from other entities, and an output unit 904 for providing signals to other entities. The input unit 902 and the output unit 904 may be arranged as a single entity or as separate entities. In some embodiments, the input unit 902 may include various sensors, such as a sound sensor, an image sensor, or any other sensor.

In some embodiments, the image sensor may include, for example, a camera, an electronic eye, a pickup camera, and the like. In some embodiments, the output unit 904 may include sound output devices such as a loudspeaker, a speaker, a headphone, and the like. Moreover, in some embodiments, the input unit 902 and/or the output unit 904 may also be an interface for communicating with devices such as external sensors, sound output devices, and the like. In other words, in these embodiments, the voice communication apparatus itself may not include these components, but rather communicates with external components through interfaces and implements the same or similar functions.

Moreover, in some embodiments, the input unit 902 and the output unit 904 may also include communicators for the processor 906 to communicate with the external, such as a wireless communication unit, a wired communication unit, and the like.

Moreover, the arrangement 900 may include at least one readable storage medium 908 in the form of a non-volatile or volatile memory, such as an electrically erasable programmable read only memory (EEPROM), a flash memory, and/or a hard drive.

The Computer program 910 may be configured as computer program codes having the architecture of computer program modules 910A-910C, for example. Accordingly, in an example embodiment when the hardware arrangement 900 is used in a voice communication device, for example, as a transmitting side, the codes in the computer program of the arrangement 900 may include: a module 910A for obtaining voice information; a module 910B for determining whether the voice information is uttered by a preset user; and a module 910C for transmitting the voice information to a peer device if the voice information is uttered by a preset user, and not transmitting the voice information if not.

Although the code means in the embodiment disclosed above in connection with FIG. 9 is implemented as a computer program module that, when executed in the processor 906, causes the hardware arrangement 900 to perform the actions described above in connection with FIGS. 1-3, however in alternative implementations, at least one of the code means may be implemented at least partially as a hardware circuit.

The processor may be a single CPU (Central Processing Unit), but may also include two or more processing units. For example, the processor may include a general purpose microprocessor, an instruction set processor, and/or a related chip-set and/or a special purpose microprocessor (for example, an application specific integrated circuit (ASIC)). The processor may also include an on-board memory for caching purposes. The computer program may be carried by a computer program product connected to the processor. The computer program product may include a computer readable medium having stored thereon a computer program. For example, the computer program product may be flash memory, random access memory (RAM), read only memory (ROM), and EEPROM, and the computer program modules described above may be distributed to different computer program products in the form of memory within the UE in alternative embodiments.

The embodiment of the present disclosure provides a voice communication method, a voice communication apparatus, and a voice communication system including a transmitting side and a receiving side, by using the solution described in the foregoing embodiments. The transmitting side obtains voice information and determines whether the voice information is uttered by a preset user, transmits the voice information when it is determined that the voice information is uttered by the preset user, and does not transmit the voice information otherwise. In this way, the identity of the person who utters the voice information may be confirmed at the transmitting side, thus the security of voice communication process may be ensured as a whole. Meanwhile, the receiving side obtains the first environment information, determines whether the voice output condition is met, outputs the voice information when the voice output condition is met, and does not output the voice information otherwise. In this way, it is possible to determine, at the receiving side, whether the current environment meets the voice output condition when the voice information is to be output, and then to output the voice information when the current environment meets the voice output condition, which can avoid the possibility that the voice information is obtained by others, and then ensure the security of the whole voice communication process.

Further, by determining, at the transmitting side, whether the audio features of the voice information are consistent with the audio features of the preset user, it is possible to determine whether the voice information obtained by the transmitting side is uttered by the preset user in the way of audio features. Meanwhile, by obtaining the facial features of the person who utters the voice information and determining whether the facial features are consistent with the facial features of the preset user, it is possible to determine whether the voice information is uttered by the preset user in the way of facial features. Moreover, by obtaining the action features of the person who utters the voice information and determining whether the action features are consistent with the action features of the preset user, it is possible to determine whether the voice information is uttered by the preset user in the way of action features, and to avoid the situation that the preset user such as the owner inadvertently triggers the voice communication, and reduce the unnecessary voice transmission. Moreover, before transmitting the voice information, optimization processing on the voice information may be performed, and the optimized voice information may be transmitted to the receiving side. Thereby, the volume of the voice information can be controlled. It also reduces the noise interference in the voice information and ensures the accuracy of the voice information in the voice communication.

In addition, at the receiving side, by determining whether there is only one voice recipient, determining whether the facial features of the voice recipient are consistent with those of the preset receiving user, and determining whether distances from other users than the voice recipient to the voice recipient exceed a preset threshold, it can be ensured that only the real user can receive the voice information when the voice is output, thus avoiding the situation that others impersonate the user or eavesdrop nearby, and improving the security of the voice communication. Furthermore, by collecting a second environment information when outputting the voice information, and stopping outputting the voice information and switching to outputting a preset voice if it is determined that the second environment information does not meet a voice output condition, it can be ensured that when other people eavesdrop in the process of voice information output, the output of the voice information may be stopped in time and other voice independent of the voice information may be outputted, thus avoiding the possibility of being eavesdropped. In addition, an interference superimposed voice may be outputted if it is determined that the second environment information does not meet the voice output condition. In this way, while ensuring that the real recipient can receive the voice information, the other user can only receive the interference voice, so that the user can receive the voice information while avoiding the possibility of being eavesdropped by others, and then the security of the voice communication may be improved. Moreover, by adjusting output volume of the voice information according to the first environment information and outputting the adjusted voice information, it can be ensured that the output voice information is compatible with the background volume in the environment. Thus, when the environment is noisy, the voice information can be outputted at a higher volume, so that the user can obtain accurate voice information, and when the environment is relatively quiet, the voice information can be outputted at a lower volume, thereby reducing the probability of being eavesdropped by others, and improving the accuracy of voice communication.

Further, according to the above method embodiment, another embodiment of the present disclosure further provides a storage medium storing a computer program adapted to be loaded by a processor and perform the aforementioned voice communication method.

The computer program in the voice communication storage medium provided by the embodiment of the present disclosure, when executed by a processor, may obtain voice information at the transmitting side and determine whether the voice information is uttered by a preset user, transmit the voice information when it is determined that the voice information is uttered by the preset user, and not transmit the voice information otherwise. In this way, the identity of the person who utters the voice information may be confirmed at the transmitting side, thus the security of voice communication process may be ensured as a whole. Meanwhile, the computer program, when executed by a processor, may further obtain the first environment information at the receiving side, determine whether the voice output condition is met, output the voice information when the voice output condition is met, and not output the voice information otherwise. In this way, it is possible to determine, at the receiving side, whether the current environment meets the voice output condition when the voice information is to be output, and then to output the voice information when the current environment meets the voice output condition, which can avoid the possibility that the voice information is obtained by others, and then ensure the security of the whole voice communication process.
